Having been spurred into looking at some vehicles, here's v4 of a European coach:

I had big problems getting the print right with a tiny clearance underneath the body. I gave up....and printed the wheels separately and superglued them on! Similarly, I had problems getting the angled shape at the rear....but resolved that one as well with a little trick!
More to follow......

As promised........here's a first print of an 18-wheel artic:

The camera can be very cruel! And informative....there's at least three issues to work on with this model. The roof of the trailer is exhibiting lack of plastic flow (lack of adhesion to next layer resulting in separation when lifting off the print bed)...and the tractor unit is exhibiting too much plastic flow ( bumps, etc...cutely called "zits").
As with the coach, all the wheels are separate and glued on.
And for the benefit of anyone who's not familiar with the scale of T, here's the two prototypes dwarfed by a pound coin:

And a third pre-production print...this time a six-wheeler box lorry:

This particular model was printed standing on it's back doors. As with the artic, its suffering from zits....so there's some work to do on this one as well.

Just need to tighten up on the settings for printing so that the zits are reduced, etc. and the prints come out cleaner. With a bit of luck, I'll have all of these available from the shop before the New Year.

Well...I've finally managed to get to a point where the print quality is at a consistent level, and no prints fail, lift off the bed, or end up with zits and bumps!
I have tonight made available in the shop four variants of coach and three variants of articulated lorry.....so, give me a headache by everyone ordering half a dozen of each!!!
I have a smaller box and flatbed lorry variant in the pipeline....and I'm looking at creating a van...to be printed in white, obviously! I'll then see if I can print some cars....but as things are getting smaller and smaller, I'm going to brick wall at some point!
Perhaps I'll enter Saturday's multi-rollover and not won lottery, win the whole of the jackpot and purchase an expensive superfine SLA printer so I can print T gauge parts in super hi-res.

Do you think that we need some sort of construction vehicles ie grinders,JCB,Rollers, etc and cement mixers,modern double decker buses, fork lifts with more cars for the layouts?
I'll have a think about what I'm able to produce from my printer. Unfortunately, FFF printers don't have the same fine resolution as some of the resin curing type printers....like Shapeways have.

Yep I have got a Da-vinchi 1.0a but can not get it to print at this small fine level like you can.
Hope to get the new Noble from XYZ at £1000.00 when the piggy bank is fat enough as this printer will do very fine detail and it is a resin printer formed by the lasers.
Will let you know when I have got this as we can then expand the T Gauge range,but this will be at the end of this now that other things are happening.
I am using obj files for my modeling and STL files for the printers.
Yep Shapeways are good but they are getting expensive.
